Letters Paton-t No. 97,285, dated November 30, 1869.

IMPROVE!) GAS-MACHINE FOR CARBURETTING- AIR.

The Schedule referred to in these Letters Patent-and making part ofthe same.

To whom it may concern: 4

`Be it known that we, E. F. Esna'rs and JOHNv v air for illuminating-purposes; and consists inthe pe cnliar arrangement in a vessel of a series of alternat ing shelves, said vessel being iilled, to aline above the nppershelf, with gasoline or other hydrocarbon, and 'in the employment ot'f a rotary pressure-blower, for

forcing atmospheric air through the gasoline in torl tuo'ns currents between said shelves, thus enrichingthe air with the inaminable vapor evolved' from the gasoline, and rendeiing it 'useful and valuable for lluminating-purposes.

In the drawings, which are a section of the carburetting-chamber and blower, and an elevation of the other parts- I A represents a vessel or chamber, of wood or metal, and of any desired shape, provided at the top with an opening, a', for filling, and with the eduction-pipe B.

'O is a series of shelves, placed in the vessel -alternatelyon opposite sides thereof.

D is a rotary pressure-blower, of any approved pat tern, rotated by a spurl-wheel, E, engaging with a pinion on the end of the fan-shaft, which spur-wheel is intended to be operated by hand, being provided with a suitable crank forthat purpose.

d is the blast-pipe of said blower, entering the carburettingcharnber A under the lowermost shelf.

F is'a gasometer, of the usual pattern, into which the eduction-pipe B of the carburetter delivers the airgas, and whence it is distributed to the. burners through the gas-main f. The gas-holder is nearly counterbalanced by a weight, g, connected thereto by a cord, h, passing over proper sheaves t in the frame-work, atthe top ofthe guide-standardsj.

The operation ofthe device is aslfollows:

The carburetting-chainber A is filled with gasoline, or otherliquid hydrocarbon, to apoint above the shelves O, through the opening a, which is then tightly closed.

The blower is then set in motion, which will force a current of 'air down the blast-pipe d, into the chamber A, under the lowerniost shelf into the gasoline, through which it passes until it reaches the end of the'- shelf, I

and rising, itis deflected by the next shelf' above, and compelled to travel. iu an opposite direction to its end, Vcontinuing its'tortuous low through the body of the liquid until it escapes at its, surface in a myriad of bubbles, enriched with the inflammable vapor of the liquid evolved by its passage through it. The pressure being continued, it is forced through the eduction-pipe B, into-the gas-holder F,which rises as it is filled, and from which -it is conveyed, through' the main f, to the burners'.

The gas-holder being. lof sufficient capacit-y, a lfew minutes expended each day in rotating the blower,

will sufiice to till the holder with enough air-gas to i1- luminate an ordinary dwelling-house until the next day.

An' air-cock may bc placedin the'pipe B, if deemed necessary, so that should,at any time, the airgas in the holder prove too rich for economical consumption, it may .be opened, and by pulling down on the cord h,

. the holder will rise and draw in sutiicient air through said cock to reduce the air-gas contained therein to the proper standard.

Whatwe claim asfour invention, and desire to se-k cure by Letters Patent, is-

The combination of the carburetting-chamher A, provided with the shelves C and with the opening a, the blower D, the spur-wheelE, the blast-pipe d, the eduction-pipe '13, provided with an air-cock, the gasorneter F, provided with .the main f, the. standard j,

the pulleys i, the cordh, and the weight g, when constructed, arranged, and operating as and for the purposes above set fort-h.

Also, in carburetting-chambers, providing the eduction -pipe with an airlcock, through which atmos-A pheric air may be drawn by raising the gasometer, for the purpose of increasing the illuminating-power of the gas.
